Run with self-built binaries.

Necessary since I want to demo features that are not yet in stable
releases, so stock Fedora 30 binaries don't show off more recent
additions.

Assumes that ~/d/$PROJ is the build directory for each of qemu,
nbdkit, and libnbd.  (Matches what was done in 2019-tech-introductions)
